Posted:7th Mar 2005There are threads about the mathematics of weaves and so on - but try to figure out what is behind this basic little move which forms (next to the circle) the fundamentals of Poi. Its not only the change of sides. Where is the pull (is there a pull?!?), what happens if you play extended/isolated Figure8, what different ways are there to play it, what happens with different Crossover Points . . . .

Ill leave the mathematical aspects to NYC and the aesthetical ones to your imagination

Posted:19th Mar 2005That's what NYC was saying,,,,today, up until now it was just the 2 dimensional stuff.

What I was suggesting was we first define the shape of the path that one poi traces, which we don't need gravity or air resistance for.

This is one of the beauties of math,,the ability to make assumptions and leave thing out and still end up with a true statement.

We can assume that air resistance is non existent, or constant due to an assumed constant velocity and shape of a poi, we can assume the force of gravity is negated by the force exerted by the spinner. ,,,,for now.

What we need first is the 3 dimensional framework to build on. and I think we have two different equations when we keep the theoretical point of rotation fixed ( by holding your hand rigid..) and by moving the point of rotation back and forth. Try the wire loop model

I've looked around online and I haven't found anything suitable to describe this shape.

As for isolations ( those ) I wonder if they wouldn't be described by using a spinning staff as a model.

Posted:20th Mar 2005NYC you have/are doing a degree in maths? can i ask you to have a look at somethign for me, in a few months when its finished (all purley theoretical and all) damn shame im not going to uberstaff now

Posted:21st Mar 2005No, No and No.Well, yes on the damn shame about you not going to Uberstaff.

I'm just particularly good at 9th grade math and 10th grade physics. Which is really all you need to understand a figure 8.

Upon further reflection, the hand motion on a figure 8 is identical to the path of the poi, just smaller. It moves left to right using a sinusoidal pattern while making circles in the wheel plane.

Don't believe me? Just do a giant figure 8 and you'll see your hand follow the exact path that the poi would on a regular sized figure 8.

Any beginning poi move can be done by having the hand do a smaller version of the desired move but just 90 degrees ahead of the poi. I could draw force arrows and crap but that would take effort.

Now, before you all get cranky, you don't HAVE to do the complete move with your hand, you can just do a segment of the move and then 'cheat' for the rest of the move. So it feels like you're just 'pumping' at certain times, and you are.

As we get more advanced, that small flick can be applied at any point in the move just to keep the poi moving. But it's always 90 degrees ahead of the poi to achieve maximum pumpage.

For example, when doing a forward butterfly with your right hand (so just the circle) you can simply pump your hand up when the poi is at the bottom of the circle. Remember when it's at the bottom of the circle, it's moving at 90 degrees to that so it's moving left to right.

It'd be pretty easy to design a robot to do a figure 8. Just have one motor go left to right at the same time that another spins.

A Riddle: If you do 2 Figure8s with 2 Poi in Splittime aka a 2beat weave, according to your equation one hand is following the other (I think this is what Z describes?!?)But for a perfect 2beat weave the handles should rotate around the same spot. One leading, one following. 2 Different Figure8s?!? Can be seen when doing a 2 beat with a staff or meteors.-> Written by: the hand motion on a figure 8 is identical to the path of the poi, just smaller.
